Now that you have chosen your batteries, you definitely will want to take care of them to prolong their life. If you let your battery just sit there, it will slowly lose its charge. Float charging, also called trickle charging, consists of charging the battery at the same rate that it is discharging. Some have found Coca Cola effective for removing corroded batteries. It allows for charge to flow between the cathode and anode. Understanding the different standards and terms used to describe batteries will be crucial in caring for your battery bank.
